Which Heads are better?
I just bought a 1985 camaro IROC Z with an original l69 HO 305...well at least i think its original, i read that all L69s came with 601 casting heads, the one i have has 416 casting heads on it.
now i am just curious as to which heads perform better? 416 heads are tpi heads correct? would the stock 190hp rating go up with 416 heads?
